Exchange 2003 SP2 Mailbox size limit reaching its max size limit, need to increase the size limit

I have a simple network, it consists of one DC running Windows Server 2003, Exchange Server running Server 2003 and Exchange Server 2003 Standard edition. I reciently had a problem with the mailbox size reaching its max limit of 16GB so I upgraded to Exchange 2003 SP2 and increased the size limit to 18GB, now it close to the 18GB limit. I configured the registery to 25GB, but it didn't take, I need help in increasing the mailbox database size limit?

Also I reciently configured all the user accounts to save there personnel folders on the file server so it would free up space in the Exchange Mailbox, when I look at the user mailboxs I can see that the size of the mailboxe has been reduiced a great deal, but when I look at the mailbox database files they dont' show any decreas in size, which is what I was trying for, can anyone tell me why this is and tell me a way to reduice the database size?

Thank you

Hi, you can follow this link for information on increasing the exchange databse size in SP2. http://www.msexchange.org/tutorials/Explaining-Database-size-limit-changes-Exchange-2003-Service-Pack-2.html

Exchange also has a feature called 'Deleted Items Retension' which basically retains all items that have been deleted for a period of around 30 days. You can decrease this retension period to drastically reduce the size of your database files if needed by following the info in this link:

hope this helps

Just noticed the Exchange Std is increasing it's size limit to 75 GB in the next SP.

http://www.microsoft.com/exchange/evaluation/sp2/overview.mspx#mailbox

Unfortunately, according to article http://support.microsoft.com/default.aspx?scid=kb;en-us;327378, it is a problem in the latest version of Exchange 2003.  They offer a patch and a registry hack, but if you don't make changes to mailbox size limits often it is probably not worth the hassle.

To quickly force an update, you can restart the Microsoft Exchange Information Store service or reboot the Exchange server.  Of course, all of your other Exchange 2003 users will lose access to the Exchange server while the service or server is being restarted.

when user delete data from the mail box it reduce the mailbox size but no the database size
to reduce database size you need to defrag your DB.
check event viewer for event ID 1221. this will tell you the space that will be free after defrag.

and this how to defrag the DB:

dsterling,

You need to do an Offline Database Defragmentation to actually reduce database size, modify this script to suit your needs

* Remenber do you need enough free space, at least double of the size of your database.

@ECHO OFF
SET E2K3BINPATH=C:\Progra~1\ExchSrvr\BIN

SET LOGFILE=X:\EXCH_mtto_LOG.TXT

SET E2K3DB="X:\Exchsrvr\MDBDATA\Database.edb"
SET E2K3DBTMP="Z:\ExchTMP\Database_MTTO.edb"

net stop "Microsoft Exchange Information Store" >> %LOGFILE%

CALL %E2K3BINPATH%\eseutil /g%E2K3DB% /t%E2K3DBTMP% >> %LOGFILE%

CALL %E2K3BINPATH%\eseutil /d%E2K3DB% /t%E2K3DBTMP% >> %LOGFILE%

net start "Microsoft Exchange Information Store" >> %LOGFILE%
